Keypirinha by itself is just a database (the Catalog) sweetened with a
small adaptive search engine and a straightforward graphical interface. Thus,
the task of feeding the Catalog is entirely left to itsPlugins.

From that point of view, we can say that the whole architecture of Keypirinha
depends on its plugins. They are responsible of finding items on
your computer, like applications, documents and bookmarks for example, as well
as offering to evaluate mathematical expressions, monetary conversions and so
on…

These items are created by the plugins and are then sorted and stored
in an internal database called the Catalog, to make making them quickly
searchable and easily executable.

By design, to configure Keypirinha and its packages requires to edit
configuration files manually. There is no graphical interface to do that.
Keypirinha uses the ini file format to read, and it only reads its
configuration.
